Abstract

Thiokol is one of the oldest and the most expensive prepolymers which also is used for insulating glass application. One of potential alternatives is modified polyether polyol, but it has poor ultraviolet light stability. This work is dedicated to synthesized alternative prepolymers and development of two component systems for insulating glass sealant application. By subjecting these particular systems to temperature, water and ultraviolet light resistance tests, it is concluded that in respect to water and UV-light resistance the systems of modified prepolymers are even better than the system with thiokol prepolymer.
